Yes, Layer 3D to Feature Class worked. I have to comment because this may save someone lots of cursing and hair pulling, not to mention time wasted with ESRI customer service. I followed the instructions for this tutorial - Construct realistic buildings with multipatch editing - located here: https://learn.arcgis.com/en/projects/construct-realistic-buildings-with-multipatch-editing/
The issue I had was extruding the building footprints. When I selected a footprint it would disappear from the ground elevation and jump to sea-level (0 ft). The instructions use Paste Special to copy the 2D footprints to 3D multipatch features. I believe Paste Special does not set the Z value of the resulting Multipatch feature, resulting in a Z value of 0. If you are following the tutorial using your own data make sure to set the elevation to Ground for the 3D Multipatch and then run Layer 3D to Feature Class after the Paste Special.
